In the Pd/Co system, the atomic flux of Pd (J(Pd)) transported across the interface is nearly same with J(Co) in the thermal spike region, while J(Pd) is always larger than J(Co) in the RED region. However, in the Pd/Au system, J(Pd) is nearly same with J(Au) in both of the thermal spike and RED regions. We have developed a model to describe the atomic transport in the RED region, which predicts that the atom with small cohesive energy has more mobility than that with large cohesive energy.
